An under-frame apparatus for a motor vehicle seat may include a basic body, a seat frame adjustable with respect to the basic body between an utmost rear and front positions, a pair of front and rear vibration levers joint-connected to the basic body and the seat frame, respectively, an adjustment arm joint-connected one of the front and rear vibration levers and including a saw teeth engagement part on a free end region thereof, an adjustment device rotatably coupled to the seat frame and engaged to the free end region to adjust a position of the seat frame with respect to the basic body, wherein the adjustment device includes a pinion gear engaged to the adjustment arm and driven by an operation unit, and an elastic member attached to the seat frame and applying a restoring force to the seat frame toward a starting position.

Under-frame for a motor vehicle seat

A seat base frame has pairs of tracks, each having an upper rail longitudinally displaceably guided relative to a lower rail and lockable by means of a locking device on the lower rail. A seat structure is connected to the upper rails, and a transverse support extends substantially perpendicular to the upper rails and is connected thereto. The transverse support is fixed in the axial direction thereof relative to the upper rails and rotatably connected thereto, wherein an actuating lever and a control lever are disposed rotationally fixed relative to each other and spaced apart from each other on the transverse support such that each can be engaged by a locking device for adjusting the locking device between a locked position fixing the upper rail relative to the lower rail and a release position releasing the upper rail relative to the lower rail.

A locking unit of a longitudinal adjustment device of a motor vehicle seat includes a latching strip, which has detent openings and detent ridges, and b) a catch unit, which includes at least two catch pins, each catch pin having a front region, a tapering region, and a shaft region. The tapering region tapers from an upper point B to a lower point A. The tapering region is delimited by a line which connects the points A and B and which does not have a rectilinear progression. The line is not located outside of a straight line connecting points A and B, and is located within the straight line over at least one third of the distance AB.

The spindle drive of an adjustment device of a motor vehicle seat comprises a spindle () and a nut unit (), wherein the nut unit () comprises a nut () made from plastic and a retainer. The nut () is in engagement with the spindle () by means of an internal thread () and retained in the retainer. The nut () has an outer jacket comprising recesses (). The retainer is configured as a tube section () comprising an inner space adapted to the outer jacket. The tube section (), in the area of the recesses () is deformed towards the inside such that material of the tube section () is located within the recesses ().

Spindle drive of an adjustment device of a motor vehicle seat

A wobble joint fitting for a vehicle seat has a first joint arm, which carries an internal gear and forms a first bearing surface, which are central to a main axis, and a second joint arm to which an eccentric gear is allocated, which comprises an externally toothed pinion and a second bearing surface. The pinion and the second bearing surface are central to an eccentric axis. An eccentric driving part is disposed in the area between the first bearing surface and the second bearing surface. Clamping parts, in a clamping state, displace the eccentric axis relative to the main axis. The eccentric driving part defines the eccentric. The rotary drive of the eccentric driving part causes a rotation of the pinion relative to the internal gear even without the clamping parts being present, wherein only play compensation is not obtained without the presence of the clamping parts.
